Guyson offers a range of dust collectors designed and developed to match the operational and environmental requirements of each Guyson blast system. Cabinet size, air input through the blast gun, the application and whether the cabinet usage is intermittent, regular or continuous are all factors in choosing the correct dust collector.

Model 41 Dust Collector

The Formula range of blast cabinets comes complete with a model 41 dust collector. This model uses fabric bag filters and is fitted with manual shake systems which need to be operated periodically to prevent dust build-up and the filters blinding. This unit is suited to light-duty or periodic usage and features four fabric filter bags.

Model C400 Dust Collector

The Guyson model C400 dust collection unit is a highly efficient unit for filtering out and collecting dust-laden air from the blast cabinet and uses a single cartridge filter.

The heavier particles extracted from the blast cabinet are deflected downwards towards the collection bin, whilst the lighter particles are retained on the surface of the filter. This model is generally used for medium-sized Euroblast cabinets and for more industrial applications/usage.

The model C400 can also be specified with a range of options including secondary filters (EPA & HEPA) and explosion relief panels - chosen when blasting potentially more explosive materials such as nickel or titanium.

Model C600 Dust Collector - for Additive Manufacturing

There is an explosive potential from some of the materials that can be involved in additive manufacturing, so the C600 dust collector has a host of features and options to minimise risks. These include; an explosion relief valve, explosion isolation valve, secondary HEPA filtration, waste bin level sensor and waste bin balance pipe. This latter item enables dust collection directly into a plastic bag (located in the collection bin hopper). This then can be quickly sealed on removal, minimising dust in the open atmosphere. Depending on the specific zone or environment, the C600 dust collector can also be specified with an optional ATEX-compliant motor, controls and switchgear. For further information download our Guyson C600 leaflet.

Model C800 Dust Collector

The model C800 cartridge filter dust collection unit is designed to draw off and collect dust-laden air from either the blast cabinet or the cyclone reclamator. The heavier extracted particles are deflected downwards towards the collection bin, whilst the larger particles are retained on the surface of the filter. The C800 is fitted with two micronic polyester filter cartridges and has an automatic reverse compressed air pulse to periodically clean the filters of dust build-up.

This model is usually specified alongside the larger Euroblast cabinets or with some of Guyson's automated blast systems - where longer blasting periods are required.

Dust Collector Options

Explosion relief panels are available where necessary - which offer greater safety when the blasting process may be potentially contributory to causing an explosion or likewise when very fine dust particles are present inside the cabinet. Other options include secondary filters (EPA & HEPA) - which are specified depending on the application and a 'bin balance pipe' - this allows the use of a plastic bin liner within the waste bin of the dust collector, facilitating easier and safer disposal of waste dust. This is particularly recommended when the AM powder material is either Nickel or Cobalt Chrome.

If you are having dust collector problems why not call Guyson now (contact details are at the bottom of this page) for an evaluation of your old dust collector and our recommendation of the most appropriate model for your blast operation? The dust collector should be matched to the anticipated operational capacity and must consider the volume of air pumped into the system, the chamber dimensions, workflow, media type and break-down rate.

Media Reclamation Cyclones

Guyson also manufactures a range of blast media reclamation cyclones, to supplement the Guyson dust collectors. The function of the cyclone reclamator is to separate out re-usable media from the dust, blast debris and undersize media. It does this by extracting everything from the bottom of the blast cabinet, the lighter particulates are drawn off to the dust collection unit. The heavier, good re-usable blast media flows back to the pressure pot thus reducing the possibility of contamination by abraded particles and debris in the media which could reduce the consistency of surface finish.

High-Efficiency Cyclone

The Guyson HE (High Efficiency) Cyclone is a free-standing unit. The HE Cyclone sits between the blast cabinet and dust collection unit and is connected to the blast cabinet via the hopper elbow and ducting.

The HE Cyclone (right photo) extracts everything from the bottom of the cabinet and deposits the used media/blast debris in a waste bin at the bottom of the cyclone. Guyson high-efficiency (HE) cyclone reclaimers are geometrically different from comparably-sized units in our standard model line-up. The dimensions of the body, cone and inlet and outlet openings of the HE Series cyclones are proportioned according to a separate formula, so the fluid dynamics result in a more sensitive separator that can be tuned for reclamation of exceptionally fine blasting media (400 Mesh) and also for preventing the dust collector from blinding when using such fine media.

How to choose the correct blast cabinet

Guyson has also created a brochure that tells you all you need to know about Guyson manual blast equipment, the options, the sizes - and how to choose the best machine for you - so why not download the 'Guyson Manual Blast Equipment Guidelines' for further background information on blast equipment selection.
